Comparing the Enthalpy Changes of Combustion of Different Alcohols Introduction The enthalpy change of combustion of a fuel is a measure of the energy transferred when one mole of the fuel burns completely. A value for the enthalpy change can be obtained by using the burning fuel to heat water. In this experiment I will be calculating and comparing the enthalpy changes of combustion of 5 different alcohols. I can calculate the enthalpy change by using the information that 4.2J of energy is needed to raise the temperature of a 1g of water by 1ºc. I will heat a measured volume of water using a fuel burner to change its temperature by 15ºC; then I will find the mass of the fuel that has been burnt. With this information I will be able to calculate the amount of energy in 1g of the fuel used. I will then plot my results into...
